Symptoms include light headedness, fatigue, palpitations, shortness of breath, chest pain, and fainting. A holter moniter confims the diagnosis. You will need blood thinner to prevent stroke,usually coumadin. Medications or ablation can treat the rhythm. Main Line Cardiology Assoc. Paoli, PA. 610-647-2400 Dr. Rudo, I am finding out a lot about atrial fibrillation, which I understand is a very commom arrhythmia. I am getting in shape recently as my family has so many risk factors for heart disease. My doctor has used the Holter monitor. Thanks for all of the information. alanstD56 13.7 years ago
